In the following pie charts the percentage of employees of a company working in 8 different countries has been given. Study these pie-charts carefully to answer the questions.
If an increase of 40% is made in the average number of female employees, working in countries III, IV and V, then their resulting average number will be what per cent of the average number of female employees ?
Country III :
Total employees = $$\frac{8}{100}$$ * 86000 = 6880
Female employees = 6880 - $$\frac{12}{100}$$ * 56000
= 6880 - 6720 = 160
Country IV :
Total employees = $$\frac{14}{100}$$ * 86000 = 12040
Female employees = 12040 - $$\frac{18}{100}$$ * 56000
= 12040 - 10080 = 1960
Country V :
Total employees = $$\frac{17}{100}$$ * 86000 = 14620
Female employees = 14620 - $$\frac{18}{100}$$ * 56000
= 14620 - 10080 = 4540
$$\therefore$$ Total female employees = 160 + 1960 + 4540 = 6660
Average = $$\frac{6660}{3}$$ = 2220
=> New average = $$\frac{140}{100}$$ * 2220 = 3108
Earlier average = $$\frac{86000 - 56000}{8}$$ = 3750
$$\therefore$$ Required % = $$\frac{3108}{3750}$$ * 100 = 83%
